New 2003 Deville owner engine jerking question.
My little brother just bought his first car, a 2003 Deville. When we got it home I decided to check why when shifting to drive I felt a familiar bump that reminded me of a motor mount job I did on my first 1990 Fleetwood. I popped the hood and had my brother shift through the gears while I watched the engine. What I saw scared me, the engine moved like something out of the movie transformers. I drove it and it shifted smooth and didn't really feel like a transmission issue. My question is, could this also be a motor mount issue? Or can someone please point be in the right direction or a possible cause of this engine jerking around like that? Also the engine is motionless less sitting at whatever gear I leave it in. It's only when shifting. I don't feel it do it while driving which it's weird to me. Any advice would be highly appreciated. Thanks.

With the car in drive, foot FIRMLY on the brake pedal, engine revved to 2,000-2,500 RPMs, the front (left) of the engine should lift less than an inch.
From your description, it sounds like there's much more movement than that just shifting through the gears.
The front, left and right mounts are hydraulic, the rear is solid. Front mount failure is fairly common, you may have more than one that has failed. Inspect all of the mounts.
This is the Catera section of the forums. You want to post in the FWD Deville/Fleetwood section. A mod can move this thread for you, don't repost.
